Abstract
Low-cost sensors, an interesting alternative for air quality monitoring in Africa.
Highlights
In Africa, the ground based air quality monitoring is often sparse, short term, piecemeal and where most of these campaigns are to test new technologies, and the scarce resources are not often targeted towards the local problems but rather at the external project priorities (Mbandi, 2020)
Electrochemical air quality sensors have the potential to fill the gap left by conventional monitoring of air pollution
The low costs of these components make it possible to deploy several copies to assess air pollution at a finer spatial resolution than could be possible with traditional monitoring setups. This solution is interesting for developing countries, which do not have air quality monitoring networks and the necessary budgets for the acquisition of conventional analyzers
Summary
In Africa, the ground based air quality monitoring is often sparse, short term, piecemeal and where most of these campaigns are to test new technologies, and the scarce resources are not often targeted towards the local problems but rather at the external project priorities (Mbandi, 2020). Electrochemical air quality sensors have the potential to fill the gap left by conventional monitoring of air pollution. The cost and size of air pollution sensors is decreasing, which means that it is possible to use portable and inexpensive air pollution analyzers (Gunawan et al, 2018).
